5oz might be kinda high, ive tried adding more molasses but it just sends my salts sky high the bacteria can only eat so much then it just starts building up, I dont clean my res anymore either, its kinda nice, lol. the bacteria have colonized my entire cloner, keeps all the bad bacteria out and helps with rooting. I cycle 5 fresh gallons of water in once a week, I dont change it all out anymore, when I cycle new water in I add a new tablespoon of recharge, the bacteria die after a while, so giving them fresh food and water will speed things up and keep it flowing. if it stops foaming they are almost dead.
